Thomas Schlichter 7c5677fd1f fix message 1 frame number calculation on NR UE
UE initiates the RA procedure with sending message 1 via PRACH 150 frames after synchronizing with the gNB.
As the frame numbers wrap at 1024, we have to calculate the frame number for message 1 using modulo calculation.

Cedric Roux ae8c0ef448 nr: add MAC PDU traces for wireshark
The T tracer macpdu2wireshark has been modified to handle the new traces.
The usage is the same as for LTE.

In NR the RACH is logged as an LTE RACH. Maybe we'll change that in the
future. Looking at the source code of wireshark, I could not find any
way to report NR RACH. Maybe they forgot it. Or I did not search correctly...
